Oops, yes, I do mean gtk.EntryCompletion.

On my system, tab selects nothing; the typed text is allowed
to remain as is.

I'm considering it.

Logically, I should be able to:

    1. Return True from the key-press-event handler for the
       EntryCompletion when a Tab is detected and an item in
       the completion list is highlighted, so that the Tab
       is ignored,
    2. In the same handler, synthesize Return and then Tab
       events in sequence, so that the highlighted item is
       inserted into the Entry before focus moves.

Of course, the handler must not create a loop in this
situation; some sort of flag might be used to prevent the
synthetic Tab from triggering the process all over again.

I'm unsure of the "correct" way to synthesize keyboard events.
And, of course, there's always the possibility that this kind
of arrangement might backfire on me... I'm a 20+ year pro at
console applications but I've only been doing GUI stuff for a
handful of years.

Thanks for your advice.
